| tellurium dioxide (TeO2) crystal | tellurium dioxide (TeO2) crystal is a kind of Acousto-optic crystal material with excellent performance, it has both excellent acousto-optic properties and high natural abundance of 130Te and double beta decay properties. Now tellurium dioxide crystal has been widely used in a variety of Acousto-optic equipment, such as acousto-optic deflector, acousto-optic modulator, acousto-optic tunable harmonic. The acousto-optic device made of tellurium oxide can improve the resolution by an order of magnitude under the same light aperture, and has fast response speed, small driving power and high diffraction efficiency, the advantages of stable and reliable performance. Therefore, TeO2 crystal is a kind of Acousto-optic device material with broad application prospects, especially acousto-optic modulator and acousto-optic harmonic wave, and its application in optical computing, optical communication and optical microscopic imaging is developing rapidly. In addition to its application in acousto-optic devices, tellurium dioxide can also be used in neutrino and dark matter research. Features: wide light transmission range: 350-5000nm large size: 50-60mm × 40-70mm high refractive index: no = 2.274;ne = 2.430 @ 633nm high quality factor:(M2 = 10-8S3/g): 795 [Silica] 1, [PbMo4] 36 |
| Use | used as a material and preservative for electronic components, also used for bacterial detection |
